Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed May 17, 1915. Serial No. 28,749.

To all whom it may concern:

Be it known that I, CHARLES A. BLODGETT, a citizen of the United Statesof America, residing at St. J ohnsbury, in the county of Caledonia andState of Vermont, have invented certain new and useful Improvements inType-Registering Mechanism for Scale- Beams, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to type-registering.

scale beams, and comprises the novel construction as hereinafter setforth.

In the drawings :Figure 1 is a cross section through a scale beam andregistering poise of my improved construction; Fig. 2 is a frontelevation thereof; Fig. 8 is a perspective view with some of the partsremoved; and Fig. 4 is a cross-section showing the scale in a differentposition.

A is the main scale beam, having graduations thereon for largedenominations, such for instance as thousands of pounds; B is the mainpoise adjustable upon the beam A; C is an auxiliary poise adjustableupon the main poise; and D is a graduated scale upon the main poise,cooperating with an index E upon the auxiliary poise for indicating thefractional weights intermediate the large denominations.

The type-registering mechanism comprises a series of type characters Fon the lower edge of the main scale beam and a second series of type Gon the lower edge of the auxiliary poise, which latter is in the form ofa bar slidably adjustable in guides H. This bar is preferably providedwith a rack face I meshing with a pinion J which may be revolved by aknob K to set the auxiliary poise in proper position.

L is a platen for pressing a ticket against the type to take animpression therefrom.

M is an adjustable handle for actuating the platen L, and N is a handlestationary upon the main poise adjacent to the handle M, forming apistol grip.

As the accuracy of the registration depends upon the exact location ofthe platen in relation to the poise, I have devised a construction inwhich said platen is guided by an integral portion of said poise. Thiscomprises a lug O integral with the back plate P of the main poise andprojecting forward therefrom. Q is a slot accurately machined in thislug 0, so as to form a ,,against the type.

guide for the platen. R- is a recess in the lug for recelving a spring Ssleeved upon the shank T of the platen, and operating to draw the samedownward or away from the type on the beam and poise. The lower end ofthe shank T extends in proximity to a finger U on the handle M, so thatwhen said handle is grasped in connection with the stationary handle Nand drawn forward, the shank will be forced upward, pressing the platenThe ticket for receiving the impression is inserted through a slot V inthe front plate W of the poise, and the arrangement is such that aportion of this ticket is beneath the auxiliary poise bar C, and theother portion below the lower edge of the main beam. Thus after bothmain and auxiliary poises are practically set, the operator by insertinga ticket and grasping the handles M and N will register the weightuponsaid ticket. The handle N is provided with a plate N which is bolted orotherwise secured to the lug O and forms a retainer for the platen. Thepivoted handle M is preferably secured to a bracket M, which is boltedor otherwise secured to the lower edge of the back plate P on the mainpoise.

One of the principal advantages of the construction just described isthat after the scale is once sealed, there is nothing in theconstruction of the registering mechanism to change, whereas withconstructions that have heretofore been used, in which the registerlngmechanism is attachable to the poise, there is always danger of somechange interfering with its accuracy.

\Vhat I claim as my invention is 1. In a type-registering scale beam,the combination with the adjustable poise, of a recessed lug integralwith said poise, a platen guided in the recess of said lug, a spring insaid recess for retracting said platen, a stationary handle having asecuring plate forming the closure for the recess in said lug, and anoperating handle pivoted to said poise adjacent to said stationaryhandle and provided with a finger operatively engaging said platen.

2. In a type-registering scale beam, the combination with the adjustablepoise, of a recessed and slotted lug projecting from said poise andintegral therewith, a platen guided in the slot in said recessed lug andhaving a shank extending through the recess, a spring sleeved on saidshank within said recess, a handle having a securing plateattached tothe face of said recessed lug, forming a closure for said recess, arockable handle, a supporting bracket for said rockable handle securedto the lower edge of said poise, and a finger on said rockable handlefor engaging the shank of said platen to press the same'upward againstthe tension of said spring.

3. In a type-registering scale beam, the combination With the adjustablepoise, of guides on said poise for a relatively-adjustable auxiliarypoise, a main beam on which said main poise is adjustable, typecharacters on said main beam and auxiliary poise, a recessed end slottedlug integral with said poise projecting therefrom, a platen guided inthe slot'in said lug and having a shank Copies of this patent may beobtained for projecting through said recess, a spring on said shankWithin said recess, a stationary handle secured to said lug and providedWith a securing plate forming a closure for said recess, a rock-ablehandle, a bracket for pivotally connecting said rockable handle to saidmain poise, and a finger on said rockable handle for engaging said shankto press said platen against the type on said main beam and auxiliarypoise, against the tension of said spring. r

In testimony whereof I aii'ix my signature in presence of tWo witnesses.
